Police said the 12-year-old boy was struck near 14th Street and Askew Avenue just before 3 p.m. Investigators said the boy ran through a stop sign when he was hit.

The driver of the vehicle that hit the boy jumped out to help.

Investigators said the child suffered serious injuries and lost consciousness after the wreck, but his condition had stabilized.

Police said there are a lot of children riding bicycles in neighborhoods this time of year and they encouraged drivers to keep a special eye out for them.

"Whether you're on a bicycle or driving a car, you just really have to be aware of your surroundings," said Sgt. Bill Mahoney of the Kansas City Police Department. "You have to be prepared to stop. A stop sign means bicycles, too."

Police said the driver who hit the boy has been cooperative and apologetic and they don't believe charges will be filed.

THEN IT COOLS OFF FOR NEXT WEEK. WE'LL HAVE THE BIG PENDULUM SWING. A LITTLE BOY HIT WHILE RIDING HIS BIKE AT 19TH AND ASKEW. KISHA HENRY HAS THE STORY. THAT'S RIGHT. YOU KNOW, THE 12-YEAR-OLD BOY WAS DRIVING DOWN THIS ROAD ON 14TH STREET AND POLICE SAY HE DID NOT STOP AT THIS STOP SIGN UP HERE. NOW, WOMAN WHO HIT HIM WAS DRIVING NORTH ON ASKEW. AS YOU CAN SEE AT THIS INTERSECTION RIGHT HERE, WITH THE BRUSH AND LEAVES IN THE WAY, THEY WOULDN'T HAVE SEEN EACH OTHER UNTIL THE LAST MINUTE, UNTIL IT WAS TOO LATE. THE WOMAN JUMPED OUT OF HER VEHICLE TO HELP AS SOON AS THE ACCIDENT HAPPENED. POLICE SAY THE LITTLE BOY WAS UNCONSCIOUS, HE WAS TAKEN TO THE HOSPITAL IN SERIOUS CONDITION. BUT LOOKS LIKE HE'S GOING TO BE OK. WHEN WE ARRIVED ON THE SCENE THERE WERE SEVERAL CHILDREN OUT HERE RIDING THEIR BICYCLES, WHICH IS COMMON FOR THIS TIME OF YEAR. OFFICERS ARE ASKING EVERYONE TO KEEP A CLOSE EYE OUT FOR EACH OTHER. WHEN YOU'RE ON A BICYCLE OR DRIVING A CAR, YOU JUST HAVE TO REALLY BE AWARE OF YOUR SURROUNDINGS AND YOU HAVE TO BE PREPARED TO STOP AT STOP SIGNS. THAT MEANS BICYCLES TOO. POLICE SAY THE WOMAN DRIVING THE VEHICLE WAS VERY APOLOGETIC AND IS WORKING CLOSELY WITH POLICE AND TRYING TO HELP IN THIS INVESTIGATION. AT THIS POINT, THEY'RE NOT EXPECTING ANY CHARGES TO BE FILED. WE WILL KEEP YOU UPDATED.
